The complex interplay of hypoxia and sleep disturbance in gray matter structure alterations in obstructive sleep apnea patients

open access: yesFrontiers in Aging Neuroscience, 2023
BackgroundObstructive Sleep Apnea (OSA) characteristically leads to nocturnal hypoxia and sleep disturbance. Despite clear evidence of OSA-induced cognitive impairments, the literature offers no consensus on the relationship between these ...

A Metabolic Obesity Profile Is Associated With Decreased Gray Matter Volume in Cognitively Healthy Older Adults

open access: yesFrontiers in Aging Neuroscience, 2019
Obesity is a risk factor for cognitive decline and gray matter volume loss in aging. Studies have shown that different metabolic factors, e.g., dysregulated glucose metabolism and systemic inflammation, might mediate this association.

The contribution of CHONS particles to the diffuse high Galactic latitude IR emission

open access: yes, 2014
This work purports to model the far infrared gray-body emission in the spectra of high-Galactic-latitude clouds. Several carbonaceous laboratory materials are tested for their fitness as carriers of this modified-black-body emission which, according to ...

Is the Universe More Transparent to Gamma Rays Than Previously Thought? [PDF]

open access: yes, 2008
The MAGIC collaboration has recently reported the detection of the strong gamma-ray blazar 3C279 during a 1-2 day flare. They have used their spectral observations to draw conclusions regarding upper limits on the opacity of the Universe to high energy ...
